Its going to be 2 inches or 2.25

I say 2".

I just replaced the stock muffler with a FlowMaster knockoff, with 2.25" inlet and outlet. The stock exhaust pipe diameter is definitely NOT 2.25". I think the exhaust shop thought it was more like 1.75", but certainly no bigger than 2".

Also, a 3.5" exhaust tip fills the bumper cutout quite nicely, much better than a 3", and not ricey looking like a 4" tip...
